selftests/mm: add configs to fix testcase failure

If CONFIG_UPROBES is not set, a merge subtest fails:

Failure log:

CONFIG_UPROBES is enabled by CONFIG_UPROBE_EVENTS, which gets enabled by
CONFIG_FTRACE. Therefore add these configs to selftests/mm/config so that
CI systems can include this config in the kernel build. To be completely
safe, add CONFIG_PROFILING too, to enable the dependency chain
PROFILING -> PERF_EVENTS -> UPROBE_EVENTS -> UPROBES.
